1 90 students in a school have visited at least two other provinces. If this represents 24% of the students in the school, how many students are in the school? Choice A

2 Possible Strategies – Estimation 24 % ≈ 25 % or ¼ 90 Whole school Which is approximately 360. Hence the whole school is 360?

3 Diagram 24% 90 students 96 % 360 students 4% 15 students 100% 375 students 4×24 4×90 24/6 90/

4 Diagram 24% = 24/100 = 6/25 (1 colour group) 4 colour groups fit in a 5×5 square Each colour group represents 90 students Coloured squares: 4×90 = 360 students 1 square is not coloured Each square is 1/6 of 90 = 15 students So, total is 360 (coloured) + 15 (not coloured) = 375 students
